I couldn't be happier with the website. The team was professional, responsive, and truly understood my vision. From the sleek design to the seamless functionality, every detail was executed perfectly. Squibble also ensured the site was optimised and mobile-friendly, making it easy for customers to find and navigate.The process was smooth, with clear communication and timely updates. Any changes I requested were handled efficiently, showing their commitment to customer satisfaction. If you're looking for a reliable website-building service that delivers high-quality results, I highly recommend them!Thank you for an outstanding experience.

West Midlands Growth Company worked with Squibble and SHC on a time-sensitive, high-impact international marketing campaign to promote the DIATOMIC CleanTech Hub under the West Midlands’ Global Growth Programme, and the results were great.From day one both agencies demonstrated a deep understanding of the brief and a shared commitment to delivering not just on outputs, but on outcomes.They delivered an integrated campaign that was data-led, responsive, and agile. The end product featured compelling assets, tailored content for international markets, and a fab digital user experience. Their LinkedIn and retargeting strategies were especially effective in generating leads, and their reporting kept us aligned throughout.Thanks to Squibble and SHC, we achieved all our KPIs and helped enhance the region's reputation as a prime destination for innovation and investment.Highly recommended for any organisation looking to partner with smart, responsive, and regionally aware marketing experts.

Lucy, Nordic Hides And Skins's Review Sourced from Google
Fantastic service from Kim and her team at Squibble LTD. We worked together at fast pace to get the new website up and running in time for our busy season which we managed to achieve. Having had lots of technical issues with our existing site it was fascinating to learn from the experts how a website should be built, hosted and managed properly. I would recommend Squibble to any business big or small. During lockdown 3- if you are looking to make improvements to your existing website I would strongly advise to go for it! Our new website has increased our sales by at least 30% since November. Lucy, (Business Owner of Nordic Hides And Skins)

Enchanted Painting Decorating's Review Sourced from Google
I recently hired Mr Digital to create a website for my painting and decorating business using Webflow, and I couldn't be happier with the results. They were incredibly helpful and explained everything clearly throughout the entire process. Communication was excellent, and they made sure I was kept in the loop at every stage. The website looks absolutely fabulous—exactly how I envisioned it. Best of all, they delivered the final product in under a month. Highly recommend!

We had an excellent experience working with Mr Digital on the development of our website - The Green Rooms using Webflow. The team was professional, responsive, and ensured the site design was both visually appealing and functional. Webflow's platform allowed for smooth customization, and the final product perfectly reflects our brand's identity. We appreciate the team's attention to detail and their seamless collaboration throughout the project. Highly recommended for anyone seeking a well-designed and efficient website

Designing a website is a creative task; finding the right person / company to do this can be complex! Thank goodness I met Nicole! Thanks to her creative ideas, practical insights, years of experience and a mountain of patience and support I now have a website to be proud of. Nicole was, and still is, the best guide when it comes to “all things online”. Her global perspective and local insights are extremely important to individuals and organizations who want to leave a strong digital footprint. I have worked with Nicole for 4 years and continue to do so ; I highly recommend you have a conversation with Nicole to discuss all your online needs.Thank you so much Julie!! XxNicole

David Anderson Review from Google

David Anderson's Review Sourced from Google
We recently commissioned LinkDigital to renew our website and we honestly could not be happier with the end result! In this day and age, lots of marketing and website development companies look the same, and are full of promises so it always feels like a bit of a gamble when you go into contract with one of them, but from the get go we knew from the amount of time and effort the team put into our enquiry that this was a very professional and hard working team. Jack initially handled our enquiry, asked lots of questions of what we wanted and seemed genuinely interested in our business and goals, and he even applied a promotional discount to our website price (which he allowed us to finance over 3 separate payments) before handing us over to the team responsible for building and developing the site, which is where Melissa came in; Melissa was absolutely fantastic and showed the patience of a saint as we added to the site, tweaked things and changed everything from colours right down to text. The site just got better and better as Melissa continued to add various details from photos to links and technical data. We are just absolutely thrilled with the finished article and it is clear to see the amount of time and effort which has went into the site. I would simply finish by saying: if you want a cheap and cheerful website which will be thrown together in a few days, you probably don’t want to use LinkDigital as they take care and time to fully assemble a proper website, which requires input from you the client and lots of information sharing, but once the effort has been put in, you will not be disappointed. Don’t have any doubts, if you employ the services of LinkDigital, you will get a quality product if you decide to go with them, they really care about the quality of what they build as it is essentially their advert for what they create, and their prices are fair when you consider the quality of the product. We would give them 6 stars if we could 😊
